    (说课稿)部编人教版三年级下册《童年的水墨画》

    一、说教材《童年的水墨画》是统编小学语文三年级下册第六单元的一篇精读课文,本文是一组儿童诗,由诗人张继楼的《溪边》《江上》《林中》三首小诗组成,以跳跃的镜头捕捉了乡村儿童的典型生活场景,展现了儿童生活的丰富多彩以及无穷趣味。 《溪边》一诗生动形象地描绘了儿童垂钓的场景。诗歌先描绘平静的溪水把人影染“绿”,再写水面钓竿上立着一只“红”蜻蜓,这一“绿”一“红”,既是和谐唯美的相互映衬,又是恰到好处的点缀,使画面充满了色彩美感;接下来,描绘了静静的溪水映着柳树、钓鱼孩子的倒影、钓鱼竿、红蜻蜓,空气都仿佛停止了流动,直到鱼儿上钩的一刹那,溪水动了,人影碎了,鱼跃人欢,画面顿时变得生机盎然。这一静一动的结合,是本诗的微妙高明之处。 《江上》描摹了一群水乡孩子江中嬉戏的欢乐场面。一群戏水的孩子,那样的调皮,像鸭群一样钻入水中,接下来“一阵水花”与“两排银牙”,将童年的烂漫快乐渲染得淋漓尽致,鲜活的画面仿佛定格在我们的脑海之中。

    四、说教法和学法:1.说教法:学习这篇课文,要让学生通过自读自悟和讨论交流,了解课文主要内容──“我”发现了什么、是怎么发现的;从中激发学生勤学好问、大胆想象、乐于探究的学习精神;体会心理活动描写对塑造人物形象的重要作用,能真实表达自己的内心感受。2.说学法:在本课的教学中,我主要教给学生学会自主探究,学会自己发现问题和解决问题的方法,学会合作学习,在合作学习中发现和解决更多的问题。引导学生学会抓住重点句段理解课文的方法。五、说教学流程:1.交流揭题,激发兴趣。引导学生回忆交流学过的课文中描写童年生活的片段,由片段交流引出“发现”,由片段交流引出“童年”,由对“童年”的交流引出课题完成“童年的发现”,激发了学生阅读课文的兴趣。2. 紧扣“发现”,初读课文。(1)默读课文,读准字音,读通句子。(2)自学课文生字词,可以用笔在文中圈出来,然后用合适的方法来解决生字词。

    部编人教版五年级下册《童年的发现》说课稿

    一、本节课的设计理念: 课题中的“发现”一词是本文的文眼,教学中引导学生从课题入手提出疑问,然后进行梳理明确主要学习任务。学生自主学习,了解“我”发现了什么,重点了解“我”是怎么发现的,理清作者童年时发现胚胎发育规律的过程。二、教材分析:本课是一篇鼓励求知、鼓励大胆想象、鼓励探究发现的课文,通过作者回忆童年时发现胚胎发育规律这件趣事,反映了儿童求知若渴的心理特点和惊人的想象力。第一部分先概述了“我”九岁时发现了有关胚胎发育的规律,却在后来因此受到惩罚。第二部分具体叙述“我”发现有关胚胎发育规律的前后经过。最后,写这个发现在几年后老师讲课时得到证实,“我”情不自禁地笑出了声,结果被老师误解受到处罚,但“我”从中获得感悟。本文故事情节充满童真童趣,语言风趣幽默,并有多处内心活动的描写,真实展现了孩子内心世界。

  • 企业年终奖发放制度形式

    企业年终奖发放制度形式

    年终奖的三种发放形式第一、guaranteedbonus(有保证的奖金):如外企普遍采用的13薪或14薪或更多,只要员工在年底仍然在岗,无论他个人的表现如何,无论公司的业绩如何,全员享受,属于“普惠”,类似于福利性质,表示公司对员工一年来“苦劳”的感谢。这里的发放规则是全员一致的,是公开的,具体数额就与每个人的基本工资水平相关了。第二、variablebonus(浮动的奖金):如根据个人年度绩效评估结果和公司业绩结果,所发放的绩效奖金,这时发放比例和数额的差距就体现出来了。通常情况下发放规则是公开的,如某某级别的目标奖(即个人表现和公司表现均是达到目标时对应的奖金)相当于多少月的基本工资(而且级别越高的人奖金占总收入的比例越高),但对每个人具体的绩效评估结果各个企业的处理方法不一样,有的对全员公开,有的不。

    新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一

    Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
